Quartus Hembly, a man without a conscience, is the ruler of the town of Copper City, having made himself rich at the expense of his workers. When Donald Keith, a young lawyer, arrives in town, a hidden spring within him is touched after Hembly viciously kicks his dog. Keith refuses to leave town and warns Hembly that he will fight to see that the people get their rights. Keith's only ally is Thora Erickson, the daughter of Hembly's henchman. Keith's opportunity to topple Hembly presents itself when he rescues Bill Wheeler, who, out of gratitude, confesses that it was Hembly who dynamited the log jam years earlier. With the lawyers and the courts in the palm of his hand, Hembly is acquitted, but the townspeople are so outraged that they capture Hembly and tie him to the whipping post. He is rescued by Keith, who forces a full confession for all Hembly's crimes and then allows him to leave town. Keith is then made district attorney, Thora becomes his bride, and Copper City becomes a decent place in which to live.
